On Rubus I would not expect H. calyculus. Do you have a photo of the spores? Also the excipulum on the flanks should be consulted whether prismatica (calyculus) or globulosa (epiphyllus and relatives).

Re:Hymenoscyphus

No, I haven't any picture of spores because they were too rare and I wasn't able to make a picture.
I will see excipulum textura.

Yes, you can say Phaeohelotium if one prefers to separate that genus. H. epiphyllus or H. monticola would be a choice. The multiguttulate paraphyses would tell for epiphyllus. Phaeohelotium do not have scutuloid spores, however. You cannot say which end of the spores is the upper end.
